Electrical materials:
Materials which allow an electric current to flow easily are known as conductors and those which prevent the flow of an appreciable current are known as insulators. Conductors and insulators are used in electrical circuits to provide paths for and to control the flow of, electric current. Practically all normal materials are either good conductors or good insulators. There are, however, a few materials which fall between these two categories and these are called semiconductors. Semiconductors will be studied in detail when we begin the electronics phase of the course.
The best electrical conductor is silver, but for most purposes its high cost is prohibitive so copper is the standard conductor material. Aluminium is an alternative, but it is not such a good conductor. Brass, which is harder than copper, is commonly used for terminals, switches etc. Tungsten and nickel are used in the construction of lamps and thermionic valves.

Amplitude: The maximum displacement of a body on either side of the mean position during simple harmonic motion is known as amplitude and it is shown by x.
Q. What are Stark and Zeeman effects? It is found that while electric or magnetic field is applied to the atom all of the spectral line split into several lines. The former ef
In whole analog to the work energy theorem for the translator motion, it might be stated for rotational motion as: Δ W rot = K rot The net rotational work given by the force
Q. Describe the construction and working of Michelson Interferometer. Explain how you will determine the wavelength difference of two components of a line by Michelson Interferom
Inductors are the electronic components designed especially for introducing a required amount of inductance in the circuit. They are coils of wires, wound around some magnetic mate
Electric charge is a physical property of matter that causes it to experience a force when near other electrically charged matter. There exist two types of electric charges, called
INELASTIC COLLISION: "The collision in which total momentum is preserved but total K.E of system is not conserved is known as inelastic collision". It is to be noted that m
FARADAYS LAW: When the magnetic flux through the coil is made to vary, an emf is induced in the coil. The magnitude of the induced emf is proportional to the rate of change of
